Order Code: 5560

Students identify and explore microbes cultured from popular dairy products like milk, yogurt, and Kefir. Teams design a monitoring method to determine when a dairy product is spoiled. Activities and topics include probiotics, fermentation, pasteurization, and shelf life. STEM extension activities include demonstrating the correlation between pH and milk curdling.

Order Code: 5561

Students discover factors that influence the growth and removal of surface microbes, design and evaluate cleaning protocols, and compare the effectiveness of antimicrobial materials. Activities and topics include surface characteristics, microbial diversity, biofilms, surface microbe identification, sanitizers and disinfectants. STEM extension activities ask How Clean Are Kitchen Sponges? And use popular mousepads to answer Do Antimicrobials Keep Products Cleaner?

Order Code: 5562

Students predict which environmental conditions are favorable to airborne microbes and then propose and carry out a strategy to collect airborne microbes using passive sampling techniques. Students construct and calibrate an impact sampler to sample an airspace and determine airborne microbe contaminate levels. Activities and topics include the presumptive identification of airborne microbes, bioaerosols, cloud chemistry and precipitation, bacterial ice nucleators, and airborne diseases. STEM extension activities include How Did Fungus Get Into King Tut’s Tomb? and Dust and Dust Bunnies.

Order Code: 5565

Students determine what factors affect microbe growth in food by designing experiments to control intrinsic and extrinsic factors, predict the probability of microbe growth on foods, and design an experiment to prove their hypothesis about the preservative effects of pickling. Activities and topics include identification of microbes in and on food, food spoilage, moisture equilibrium, water activity,nutrients, and food as an ecosystem. STEM extension activities include evaluating the effectiveness of garlic as an antimicrobial agent and the demonstration of Koch’s Postulate.

Order Code: 5563

Students research the process of soil formation, soil characteristics, and the influence of environmental conditions on soil microbe populations. Students assess and sample various soil ecosystems using the surface contact impression technique, dilution technique, root wash technique, and the Rossi-Cholodny buried slide contact transfer technique. Microbes are identified and enumerated to calculate microbial diversity.
